AIR MAIL

Where today’s air came from

The air arriving over Wenonah about 5,000 feet above the ground was over British Columbia three days ago, and over the central Plains a day ago, about 2,470 miles back along its path. It came down from about 10,900 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the central Plains. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK IN 2003 Nov. 17–18, 2003

The wettest two days this week has seen

4.54 inches of rain fell in two days, the most for this week of the year since records began in 1890. The next wettest, 2.92 inches, fell in 1978.

THE GROUND

What Wenonah stands on

Wenonah’s center stands about 670 ft above sea level. Within three miles the land runs from 640 ft to 740 ft, a difference of 100 ft: gently rolling country.

Under the town center the state geologic map shows Bond Formation (shale, sandstone, limestone), from the Late Pennsylvanian, 304 to 307 million years old.

The section below crosses 2 rock units mapped at the surface.
